My current thinking in response to that is that using islice is a decent
solution except that it's not obvious. You have to jump outside of the thinking
about the destructuring capability and consider what else could be used to
help. Probably, first thing that _would_ come to mind from outside would be
slicing with square brackets, but that would restrict the solution to only
work with sequences and not other iterables and iterators as islice does.
That brings up a tangential idea. Why not allow square-bracket indexing of
generators instead of having to import and utilize islice for that?
Because generators don't have a common (sub-)type, so there's no class
to put the relevant __getitem__ method on.
How so?
>>> def mygen(): yield 42
...
>>> type(mygen())
<class 'generator'>
